2 minutes till midnight...

Well it is just before midnight, the night before my last day at work here in Brum. We got the rest of our readings done today on the rheometer using the "Dynamic Strain Sweep" mode, which is awesome considering I had my doubts about if we would be able to get any results or not. It turns out that the viscosity* readings of G' and G'' do show some noticeable differences in the 3330 and 3340 samples.

Matt, Nick, and I got some "jacket potatoes" (baked potatoes) for a snack before doing cleanup duty at the Materials Engineering graduation banquet. We saw Dr. Kukureka there, who had just returned from China. He came up to the lab and talked with us for a while about what we had been doing in the lab. We called it a day, and made plans for tomorrow: try a Dynamic Frequency Sweep profile and secure all the data from the past month and put it on my laptop.

I actually have begun to understand a good bit more about the Rheometer from just working with it for the past two days. I originally thought that the vast amount of variables was a little overwhelming, but I have narrowed it down to Frequency, Strain %, and Temperature as the primary variables of interest. The Dynamic Strain Sweep profile keeps a constant temperature and constant frequency while going through a range of Strain %.

Anyways, i'm going to bed on time for once this trip.
